We structure our data collection in such a way that information is
stored in several HDF5 files (one for each set of experiments).
Within each HDF5 file, we store data from multiple, related
experiments.  Each experiment has its own node in the HDF5 file, with
each node containing a table of data (along with several arrays,
attributes, etc.).  The table under each experiment node is identical
in structure.  Is there a simple way to construct a query that
traverses across the table in each node (and each file)?  If not, is
there a way to create a virtual table that reflects some view of the
parent table?  For example, we could use a single master table to
store all of our data along with an experiment ID (to facilitate
querying), but we still want each experiment node to have a view of
the master table showing only the data for that particular experiment.
